interior, but I have to regret that every one of them died 
before reaching the coast. 
The other samples consist of bark of the root of species 
No. 1, and an extract obtained by incision from the tree, and 
evaporated in the air. Mr. Henry, Jr. and myself, having 
submitted to analysis these different products, we have as- 
certained : — 
1st. That the leaves and seeds of the Calisaya bark do not 
contain the vegetable alkalies found in the bark. 
2d. That the root contains them as well as the red and 
yellow colouring matter. 
3d. That the inspissated juices obtained by incision are com- 
posed of the same principles as the aqueous extracts of the 
bark of the tree.* — From the Journ. de Pharmacie, Oct. 1835.

(Extract.) 
Preparation. The root of the B. vulgaris is to be contused 
and a sufficient quantity of boiling water poured on it, it is 
suffered to digest for some hours, being frequently stirred ; the 
fluid is then decanted and the operation repeated. The residue 
is subjected to pressure, and the whole of the decoctions fil- 
tered and evaporated to the consistence of a soft extract. This 
is several times treated with boiling alcohol 0.8200 and the 
tinctures decanted from the residue, they are then to be filtered 
and distilled, so as to obtain most of the alcohol, the residue 
is placed in a flat capsule in a cool place. In twenty-four 
hours, it will be found filled with small plumose crystals of a 
yellow colour, these are to be separated as much as possible 
* The whole proceeding of the experiments made by Messrs. A. Delondre 
and Henry, jr. are given at full length in the Journal de Pharmacie ; but, for 
want of time, I have contented myself with giving their conclusions. E. D.
